unknown ISC error 335545106

[marcel thiele]

Hey there.

For 1 week i got this Error if i try to open Vario7. The only thing what changed is, that i installed Windows updates trough the days.

What i think is that maybe some drivers changed... Somebody else got a similar error and maybe a solution?

Regards,
Marcel

335545106 is "Error occurred during login, please check server
firebird.log for details". Check the firebird.log for the associated
error. Likely the error in the log is "No matching plugins on server",
which means the client wanted to try different authentication plugins
than the server has configured.

The fact the error is missing means that you're using Firebird 3.0 or
higher, with a fbclient.dll (or driver) which only has error messages
for Firebird 2.5 or lower. The error itself could be caused by using a
fbclient.dll of Firebird 2.5 or lower with Firebird 3.0 or higher which
doesn't have Legacy_Auth configured. Use a newer fbclient.dll (or, not
advisable, configure the server to accept Legacy_Auth, and make sure
users exist for Legacy_UserManager).

Hey Mark!

Thanks for the fast reply!

I checked the fbclient.dll and they are alle "the old"... from 2011...

I found finally the logs from the program and there was a error:

XNET error: XNET server initialization failed. Probably another instance of server is already running.   operating system directive CreateMutex failed

The other program already runs 2 years with the old one and we had NEVER problems.... but if i stop the new service the old program works again! 

Thanks a lot and have a nice weekend!

Regards,

Marcel

Everyone know that to let two different Firebird servers to run
simultaneously you need to configure them:

1. Different TCP ports for INET protocol.
2. Different Named Pipe name for WNET protocol.
3. Different IPC shared memory name for XNET protocol.

It is a basic knowledge of every Firebird administrator written in
firebird.conf itself.

In Firebird I'm only Customer of different products which use Firebird :/

IPCNAME was the key in my case :-) Thats what i could change in one of the application configs.

Thank you very much and have a great week.
